-I/:wvilldescribe one'form of "sign" embod wenn thejgnovel features thereof `1n claims.'

the accompanying drawings, Figure 1 isfa view showing in front elevatlon, partly4 sectioned, one form of signal embodying my invention; 1lff`ig:12'isa1view'showingin side 3 is a sectional view'on thehne -III of Fig. 1 looking in the direction indicated ,by :the arrows;" ig. 4;- is a diagrammatic `view showing one-arrangement of circuits for the control, ofy the shown ilar parts in'each of the views.

Referring to Figs. 1, 2`and 3, the referates aV support or in which all the other parts of the signa are mounted. As. hereV shown, this casing is arranged'to stand on the ound, but it is understood that it may equa y well casing 40 be designed fobs'usgension from '-a -pole a.

or other structure ove' the lstreet level. Mounted in the casing 5, and at right angles to eachother, are two-direction-mdicating devices 6 and..6*each ofl which devices is '45 arranged to oscillate on a horizontal axis.

As here shown, device 6 comprises two members located one on each side of a box 5* constituting part of the casing 5; the two members being fixed respectively to two shaft sections 7 and 7*, which Vare in axial alinement 'and are journaled in .suitable bea'ri in the box 5*. `The other direction-in 1-V ;cating device 6* also comprises two members located respectively on opposite sides of the box 5*,*but these membersare both fixed to States, residing at ventio'n, and 'then point outelevation the signalshown l; Fig.

go single shaft 8 which extends through the x 5*. l The. shaft 8 is intel-locked rwith theI two shaft sections 7 and 7* in the manner which I'will now explain. Fixed to -shaft section 7 is a bevel gear 20, and fixed to shaft sec.

gears both mesh with a beve is fixed to thethrough shaft seen,'therefore, that if shaft 8 is rotated shaft 7 will be rotated in one direction shaft 7* will be rotated in the other direction. As here shown, each 'member of leach,r 4

isllat, although Ido not wishnto limit myselfl to this vcon struction, and the shafts are interlockedin-- such relative manner that when the ,two

directionindicating device members 6 'are vin the vertical plane both members 6* are in'the horizontal plane, and when members 6 are in the horizontal plane,

tion 7*, is al similar bevel ear 21, These l gear 22 which 8. It will be both members 6* are in the vertical pla'ne.

The tvvomcmbersof',v each device may Alie word .Stop may Vbe painted thereon as a further.I ,indication if desired. It will now 4constructed so that the device; has the a ,pearance of an arrow as shown, endgt e be seen that if a pedestrian or a driy'er of 'a vehicle approaches the signal from. the direction in which Fig. V1A is taken and the.in' l dicatingl devices are in-'the' positions shown" in that view, information is' given that traflic l 'is 'then' in Vt e other direction and that such person .shou .d stop; when, however, devices 6'and 6* are reversed, the si nal will have the appearance of Fi Q, in icatng to the person 'approaching t 1e same that-traffic is in the direction' in which he is proceeding and that it is therefore safe for him to cross A, 4'

the street intersection'. y e The directiomindicating devices may be operated by any suitable -type of motiveby a solenoid device' comprising two solenoids 10y and 11 andy a pliinger 12. The plunger "is attached to .the lower end of a'4 rod 13 rwhich extends upward through the casingand is formed at its upperend into a he'nd 14 having a slot 15 which fits loosely over the shaft 8. 4'This head is provided with a pin or stud 16 which coactswith a jaw 17 attached rigidly to the shaft 8. 4llVh'en the parts arc iu the positions' Shown in Fig. 1, upward movement' of the rod 1'3 will canse rotation ofshait 8in clockwise direction owing to thcwcoaction Vof stud 16 and device. As here shown they 'are operatedl jaw 17. Tho oscillations ofshaft 8 are limited by two collars 23 and 24 fixed on rod ,13, whichcollars are so' located that shaft 8 can oscillate through an angle of 90, that is, through such an angle that device 6* moves from the horizontal to the vertical position. Shaft 8 is held firmly in each extreme osition by a'springI 18, one end of which a uts aga-inst a washer 41 slidable against the top of the box 5' and the other end of which abuts against; a block 19 pivotallyattached to thegaw 17. Integral with the block 19 is a rod 19 which serves as a guide for the spring.

he solenoid device M' is controlled by a eircuitcontroller I comprising two separate contact fingers 25 and 26 (see Fig. l) having separate push buttons p and p. With the parts'in the position shown; if contact 25 1s pushed inwardly, the Aupper solenoid l0 will be energized through a circuit from battery 27 through wires 28 and 29, contact 25, wire,30, solenoid 10, wires 31 and 32 to the battery. Solenoid 10 when thus energized raises plunger 12, and so swings device 6 tothe horizontal position .and device During this movement spring 18, is, of course, compressed and. towardthe end of the movement,this.spring,`wheh has then passed the dead-center 'positin, assists solenoid 10 in swinging .tlie indicating members to their i Vfinallpo'sitions`; this spring .also holds the.

members firmly in position after solenoid 10 is de riergized'by the removal of pressure When itis. desired to swing the indicating devices back to the positions viniwhich they are shown 4in the drawings, contact 2G is pushed inwardly thus energizing solenoid llfthroughthe following circuit: from bat- -tery 27, through wires 32 and 33, contact 2Q, wire '34, solenoid 11, wires 35 a=:d 28, to battery 27. Solenoid 1,1 being thus energized draws plunger 12 'downwardly and pin 16 coat-.ts with jaw 17.to swing shaft 8 countcrclockwise as viewed in Fig. 1, thus returning members (i to the vertical position and members (1 to the horizontal position. These Omcn'ibers are held firmly in their respective positions by spring 18 after the solenoid circuit is opened by-releasing contact 26. Y

Mounted on the top of the c asing 5 is a 4globe 40,. which contains'an Incandescent lamp 4U", shown in Fig. ,3. This lamp is illuminated through a circuit which is closed only when push button contacts 25 and 26 are in'their normal positions, the circuit being from battery 27, through wires 32 and 33, contact 26, wire 37. lamp 40, wir(` 36, contact 25, wires 2%) and 2H, to battery 27. It will be seen that this lamp is normally illuminated but is momentarily extinguished each time that either contact 25 or 2U is op- -therein within the scopeof the appended claims without departing* from the spiritV and scope of my invention.
